Available in PDF, EPUB and Kindle. Book excerpt: The introductory sections contain a brief discussion of the general methods of producing fiber-reinforced composites and of the theory of fiber-reinforcement of metals. The body of the report describes research on fiber-reinforced metal matrix composites, and is organized according to metal matrix materials. For convenience, the report is divided into two sections: Low density matrices (including aluminum, magnesium, and titanium and their alloys) and high density matrices (cobalt, copper and its alloys, iron, lead-tin alloys, nickel and nickel alloys, silver, tantalum, and tungsten).

Download or read book New Developments in Welding Steels with Yield Strengths Greater Than 150 000 PSI written by Robert Melvin Evans and published by . This book was released on 1965 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report summarizes the advancements made in the development and welding of steels possessing yield strengths greater than 150,000 psi. Steels discussed include the medium carbon, low-alloy martensitic steels; low carbon alloy martensites; and nickel maraging steels. Almost all programs which have the objective of developing high-strength steels have an equally important phase concerned with filler metal development. Filler metals are also discussed. The new welding processes discussed are Narrow-Gap welding, electron-beam welding, plasma-arc welding, high-frequency resistance welding, electroslag welding, laser welding, and interrupted-arc (dip trasfer) MIG welding.

Download or read book Weldability of High strength Aluminum Alloys written by Robert Melvin Evans and published by . This book was released on 1966 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: This memorandum describes the fusion-welding characteristics, mechanical properties, and stress-corrosion behavior of high-strength, weldable aluminum alloys. These are defined as alloys in which sound welds can be produced and in which at least 50 and 70 percent of the maximum base-metal strength can be retained in the as-welded and post-weld-treated conditions, respectively. Careful selection of joining method and filler metals as well as close control of joining-process parameters is necessary to produce high-strength aluminum weldments. Highest strengths and weld-joint efficiencies in high-strength weldable alloys are achieved with the use of postweld aging and/or mechanical treatments. The best combination of highest strengths and good welding characteristics is found in the 2000 and 7000 alloy series. As compared with the 2000 and 5000 alloy series, the 7000 alloy as a class suffer three major property disadvantages: (1) their tendency to be notch sensitive, (2) their tendency to exhibit low toughness at low temperatures, and (3) their much greater susceptibility to stress-corrosion cracking. Nonetheless, several relatively new 7000 series alloys have been developed which show reasonably good notch toughness to -423 F and which are considered competitive with the 2219 and 2014 alloys for cryogenic applications.
